FME Transformers: 2024.1
FME Transformers: 2024.1
SharedItemIDSetter
Sets Shared Object IDs onto the front and/or back sides of geometries.
You may also, at the same time, generate the texture coordinates of the surfaces that are affected. Texture coordinates are only required where Raster textures are used.
Geometry Definition IDs can be set on existing Geometry Instances. New Geometry Instances can be created by setting a Geometry Definition ID on a single Point, or on an aggregate containing a single Point. The Point coordinates will be the insert location of the new Geometry Instance, and any matrix that may exist on the Aggregate will be used as the placement matrix (scale, offset, rotation, etc.) for the new Geometry Instance.
Setting a Geometry Definition ID on a single oriented Point will result in the Point’s orientation being used as the placement matrix for the new Geometry Instance.
Configuration
Input Ports
Input
Each input feature should contain the geometries to set Shared Object IDs on, as well as the IDs to use, stored as traits or attributes.
Output Ports
Output
All input Geometry features that have had Shared Object IDs set.
Unmatched
Input features where no geometry part matches the Geometry XQuery.
<Rejected>
Input features that could not have a Shared Object ID set.
Parameters
Item To Set
Item Type |
Select the type of items to set:
|
||||||
Side |
When Item Type is Any, Appearance, Texture, or Raster, select the sides to set:
|
||||||
Geometry Part Selection |
Use this parameter to isolate only a portion of the input geometry. If no criteria are specified, the action will apply to the entire geometry at all levels. Selection can be based on structural location, geometry name, type, appearance information, traits, trait storage types, or definition reference. The syntax used is a restricted set of XQuery, where the return clause is fixed. The basic Geometry XQuery dialog allows you to construct simple selection queries by automatically writing the necessary query based on specified test clauses. Clicking the Switch to Advanced button opens the Advanced Editor, which allows you to type a query free-form, for more expressive queries. Note Once you switch to Advanced mode, you will have to clear all parameters before you can return to Basic mode.
A hierarchical geometry is represented as nodes of type geometry, with attributes containing information about traits, type, and name for each geometry. |
Shared Item ID
Retrieve Shared Item ID |
Select the source of the Shared Item ID:
|
Shared Item ID Attribute |
When Retrieve Shared Item ID is From Attribute, specify the name of the attribute containing Shared Item IDs. |
Shared Item ID Trait |
When Retrieve Shared Item ID is From Trait, specify the name of the trait containing Shared Item IDs. |
Texture Coordinate Generation
Use Existing Texture Coordinates |
When an appearance with a raster texture is set, each part of the Geometry that is affected will also require texture coordinates.
|
||||||||||
Texture Mapping Type |
Specify how the texture defined in an appearance style is mapped onto the surface. This is only applicable to textures which have raster images.
|
||||||||||
u Origin Offset |
Specify how the texture is shifted in the u direction. |
||||||||||
v Origin Offset |
Specify how the texture is shifted in the v direction. |
||||||||||
Texture u Repeat Factor |
Specify the number of times the texture is repeated in rows. |
||||||||||
Texture v Repeat Factor |
Specify the number of times the texture is repeated in columns. |
Editing Transformer Parameters
Transformer parameters can be set by directly entering values, using expressions, or referencing other elements in the workspace such as attribute values or user parameters. Various editors and context menus are available to assist. To see what is available, click beside the applicable parameter.
How to Set Parameter Values
Defining Values
There are several ways to define a value for use in a Transformer. The simplest is to simply type in a value or string, which can include functions of various types such as attribute references, math and string functions, and workspace parameters.
Using the Text Editor
The Text Editor provides a convenient way to construct text strings (including regular expressions) from various data sources, such as attributes, parameters, and constants, where the result is used directly inside a parameter.
Using the Arithmetic Editor
The Arithmetic Editor provides a convenient way to construct math expressions from various data sources, such as attributes, parameters, and feature functions, where the result is used directly inside a parameter.
Conditional Values
Set values depending on one or more test conditions that either pass or fail.
Parameter Condition Definition Dialog
Content
Expressions and strings can include a number of functions, characters, parameters, and more.
When setting values - whether entered directly in a parameter or constructed using one of the editors - strings and expressions containing String, Math, Date/Time or FME Feature Functions will have those functions evaluated. Therefore, the names of these functions (in the form @<function_name>) should not be used as literal string values.
Content Types
These functions manipulate and format strings. | |
Special Characters |
A set of control characters is available in the Text Editor. |
Math functions are available in both editors. | |
Date/Time Functions | Date and time functions are available in the Text Editor. |
These operators are available in the Arithmetic Editor. | |
These return primarily feature-specific values. | |
FME and workspace-specific parameters may be used. | |
Creating and Modifying User Parameters | Create your own editable parameters. |
Dialog Options - Tables
Table Tools
Transformers with table-style parameters have additional tools for populating and manipulating values.
Row Reordering
|
Enabled once you have clicked on a row item. Choices include:
|
Cut, Copy, and Paste
|
Enabled once you have clicked on a row item. Choices include:
Cut, copy, and paste may be used within a transformer, or between transformers. |
Filter
|
Start typing a string, and the matrix will only display rows matching those characters. Searches all columns. This only affects the display of attributes within the transformer - it does not alter which attributes are output. |
Import
|
Import populates the table with a set of new attributes read from a dataset. Specific application varies between transformers. |
Reset/Refresh
|
Generally resets the table to its initial state, and may provide additional options to remove invalid entries. Behavior varies between transformers. |
Note: Not all tools are available in all transformers.
For more information, see Transformer Parameter Menu Options.
